Delay Line Stage, Includes Controller, 325 mm Travel

The DL family of stages is optimized for ultrafast spectroscopy applications that require repeatable and precise delays (0.5 fs). The controller is included with the stage, and a user-friendly GUI can be downloaded. Three travel versions and seven beam kits are available.

The DL controller GUI is a user-friendly way to interact with the stages. It can be used to initiate absolute and relative position moves, user-defined scan sequences, cycling and jogging movement. Both the position of the stage (in mm) and amount of delay (in psec) are displayed in the GUI. The software is compatible with Windows 7 and higher.

Precision position feedback is provided by a linear glass scale encoder mounted inside the stage. The encoder signals are interpolated by an integrated motion controller with nanometer resolution for outstanding position sensitivity, repeatability and stability.

To ensure position stability in the amount of delay, the step-and-settle time for DL stages is less than 0.2 sec for short moves.

To facilitate setup, beam kits consisting of retroreflectors, mirrors, mounts, and other optomechanical parts, are available to suit various wavelengths and delay line configurations. Single, double and quadruple-pass versions are offered.

The DL stage has been designed to be mounted on standard breadboards (with a 0.2 mm flatness). Pads minimize the effect of the table on the pitch, yaw and roll performance of the stage. To reach the specifications stated, stages must be fixed on a plane surface with a flatness of 5 μm with washer under each fixing screw head (max. tightening torque for mounting screws: 3 Nm).

Clamps allow for locating the stage where the standard hole pattern is not available. Suggested base clamps are BC-5 and BC-6.
